I Application filed January 29, 1904. Serial No. 191,169. (No model.)

To all whom it may concern/.-

Be it known that I, WILLIAM AcKERMAN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Matrix LocatingMechanism for Type-Casting Machines, of which the following is aspecification.

This invention relates to a mechanism for I O locating thematrix withthe desired charactercavity over the mold of a machine whichautomatically casts, sets, and justifies individual type.

The object of the invention is to minimize 5 the movements of thematrix, and thereby reduce the wear of the parts, allow an increasedspeed, and eliminate most of the noise and shock incident to themovements of the matrix and its carriage.

The invention is illustrated as embodied in a mechanism which isespecially designed for carrying and locating the matrix of a graphotypemachine of the character of that illustrated and described in UnitedStates Letters 5 Patent No. 609,098, issued to G. A. Goodson August 16,1898. Previously the matrix of such a machine'has always been carriedback to the same extreme position for relocation after each type hasbeen cast, entailing much 3 movement for the entire carriage and theconsequent wear, noise, and shock incident to the long movement of theheavy carriage mechanisms. In the present instance the matrixcarriage isconstructed in two parts. The

heavier, which carries the matrix, at first moves only a part of thedistance back, and the lighter, which is elastically connected with theheavier, only travels the entire distance back after every type has beencast,

4 and then the two parts come together after the pins have been raisedfor stopping the carriage and locating the matrix.

In the views, Figure 1 shows a plan of a carriage and matrix of amachine of the type illustrated in the Goodson patent mentioned, withthe carriage parts, the matrix, and operating mechanisms in thepositions which they would occupy when a type is being cast. Fig. 2 is asimilar view showing the carriage parts separated and in such positionsas they would occupy just before the matrix is located. Fig. 3 shows adevelopment of the carriage-operating cam. Fig. 4. shows a bottomview'of the carriage and matrix. Fig. 5 shows a plan of the frame andthe carriage 5 5 parts, the matrix and the operating mechanisms beingomitted. Fig. 6 shows an edge view of the frame with the carriage, andFig.

7 shows a section of the frame and carriage on the plane indicated by ma: on Fig. 5.

The rectangular frame 1 may be attached to the machine-bed in anysuitable manner.

It is preferably hinged at the back end, so that the matrix may be swungdown close to the. mold or may be lifted away from the mold.

The side edges of the main carriage 2, which is made as light aspossible, are fitted into ways formed in the inside edges of the frame,Figs. 5 and 7, so the carriage is free to move back and forth. Extendingacross the carriage near one end are a pair of bars 3, and supported byand movable transversely of the frame on these bars is the matrix 4:,which has in its under face the cavities, Fig. 1, in which thecharacters are cast, and in its upper face the perforations, Fig. l, inwhich the centering-pin 5, held'by the yoke 6, that is fastened to theframe, is thrust to insure the exact location of the matrix-cavities.

The supplementary carriage 7 is mounted 30 on the main carriage with itsedges fitted into ways, so it may have an independent movementlongitudinally of the main carriage. Two springs 8 elasticallyconnectand draw together the main and supplementary car- 8 5 riages. Thesupplementary carriage is also connected by a spring 9 with the yoke.The

springs 8 tend to keep the main and supplementary carriages together,and the spring 9 tends to draw both carriages and the matrix 9 to theforward limit of their movements.

A lever 10, pivoted upon one side of the frame, has an end adapted toengage the front side of a block 11, that projects upwardly from thesupplementary carriage. The other end of this supplementary-carriagelever is engaged by the end of the lever 12, which has anantifriction-roll 13 in engagement with the cam 14: on the maincam-shaft of the machine. A lever 15, pivoted to the same side of theframe, has an end held in engagement with the rear side of a block 16,that projects upward ly from the main carriage by a spring 17. The otherend of this main-carriage lever is engaged by a lever 18, which has anantifriction-roll 19 in engagementwith the cam 20 on the main cam-shaftof the machine. A spring 21 between the cam-levers holds the rollsagainst the cams.

The dam 14 is so timed that after each type is cast the lever pushes thesupplementary carriage back to the limit of movement of the carriage,and the two springs 8, which connect the supplementary carriage with themain carriage, tend to draw the main carriage back with thesupplementary carriage. The cam 20 is so timed that the lever is allowedto oscillate and the main carriage move back until approximately half ofthe movement of the supplementary carriage has been made. Then the camcauses the lever 15 to stop and temporarily hold the main carriagefromfurther backward movement, while the supplementary carriagecompletes its backward movement. Then after the desired stop-pin hasbeen raised in the usual manner by the operation of the machine the camsrelease the levers, so that the carriage will be drawn forward until itis stopped by the pin that has been raised.

In the organization shown if one of the first series of pins 22 has beenraised the supplementary carriage is held by the engagement of the hook23, Figs. 1 and 6, attached to its under side, with the rear edge of thepin that is raised. Then when the lever 15 is freed by its cam the maincarriage is drawn backwardly by the pull of the springs 8 until itcloses against the supplementary carriage.

This of course locates the matrix in the desired position. If one of thesecond series of pins 24: has been raised, the supplementary carriage,when the cam 14 releases the lever 10, is not held, but is drawnforwardly by the spring 8 against the main carriage. Then both carriagesmove forwardly together until stopped by the engagement of the hook 25,Figs. 1 and 6, attached to the under side of the main carriage, with therear edge of the pin that has been raised. On the under side of the maincarriage in front of the hook 23 on the supplementary carriage is aplate 26, Figs. 4: and 6, which prevents any of the supplementaryhook-holding pins from rising up and preventing the movements of thecarriage after one pin has engaged a hook. 1f the supplementary carriageis stopped by one of the first series of pins when the main carriage isdrawn backwardly by the springs against the supplementary carriage, therear edge of the plate 26 engages the front side of the holding-pin andpositively stops the main carriage in its backward movement.

The matrix is carried longitudinally of the frame into position by themain carriage; but the main carriage may be stopped by either of thepins which engage it or may be stopped by either of the pins whichengage the supplementary carriage. If a main-carriage stopping-pinisraised, the supplementary carriage when released by its lever is drawnforwardly to the main carriage by the springs. If a pin stops thesupplementary carriage, the main carriage when released by its lever isdrawn backwardly to the supplementary carriage by the springs. The maincarriage at first makes only half a movement, it being held by the lever15 until a pin has been raised into proper position to stop either themain carriage or the supplementary carriage at the correct longitudinalposition, and then under the influence of the springs the main carriagemoves baclavardly or the su1')plementary carriage moves forwardly untilthe two carriages come together and are held by the raised pin with thematrix in the proper longitudinal position;

The lever 10 has a iinger27, which engages the end of a sliding bar 28,that at its opposite'end engages a friction-roll on the end of the lever29, pivoted to the side of the frame. This latter lever has afriction-roll that lies between a pair of lugs 30 on a slide 31, thathas a hook which engages a groove 32 in one edge of the matrix. Thislever and slide move the matrix transversely of the carriage.

The series of pins 33 are raised by the usual mechanism of the machinefor stopping the slide and holding the matrix in the proper transverseposition. A spring 3 1 draws an end of the lever against the end of thebar. The pins 33 when raised engage the hook 35 on the under side of theslide, as in the old machine. The matrix is moved transversely of thecarriage at the same time that it is being moved longitudinally of theframe with the carriage.

By making the matrix-cavities of the characters inost commonly used nearthe center of the matrix the motion of the matrix is very little aftereach type is cast, for with most of the characters it would only bemoved back a slight distance, if any, before being located for thecasting of the next type.

With the prior machines the matrix as each type has been cast has beendrawn back to its full extremity and then moved forwardly until stoppedin the proper location to form the character desired. With the presentconstruction, the matrix being on the main carriage is only moved backhalf of the regular distance, and then if it is necessary to bring theproper character into position it is moved still farther back; but if itis back far enough then it only moves forward a slight distance.
